How much does it cost to outsource the manufacturing of fiber optic splice boxes
For most commercial projects, expect to pay $50–$150 per fusion splice point - but that number can swing in either direction based on the factors below. The cost to outsource manufacturing is the total of all expenses incurred when hiring a third party to produce goods or components instead of manufacturing them in-house. Fiber optic splicing costs vary widely depending on project size, location, fiber type, and site conditions. I usually bill T&M, but it works out to about $175-250 for setup/teardown per site and $4-7 per fiber for prep in a new tray in an existing case and splicing depending on if it's flooded or dry cable. Add another $50-75 to prep a new case endspan or $100-150 for a new case midspan with overcut on. Understanding these factors can help businesses and individuals budget effectively for fiber optic.
